USRP N210 and B210 Output Different Binary Data

[sergio_polyuaae]

I'm currently using GNU Radio to connect with both USRPs to record GNSS data.

However, the N210 and B210 output different binary data. Attached are the images. 

The B210 achieved more favorable binary data (the neater one). Can someone tell me the reason for why both USRPs output different binary data?

I'm expecting the same binary data from both USRPs, since they both use the same GNU Radio blocks.
